Sir,I am a 4x4 trailer manufacture from South Africa and have designed a independant suspension for the trailers which I want to export to Australia. I am looking at installing disc brakes on the suspension which will mean I will need hubs with load carring capacity of 2000kg per hub, discs and calipers. Spares must be available at any spare centre world wide.Can you help me with this request and what will the cost be per pareRegards,Thanks.
